When you use a Kerberized application to connect to a remote host, the application, the KDC, and the remote host perform a set of rapid negotiations. When these negotiations are completed and the application has proven your identity on your behalf to the remote host, then the remote host grants you access.
You can log in remotely by using ssh or ftp.
After installation, the ssh command is the only network service in Oracle Solaris, including Kerberos, that accepts network requests. See the ssh(1) man page.
The OPTIONS section in the ftp(1) man page describes the Kerberos features in the FTP application. Your administrator must configure access to FTP.
